As an analogy - if I push you head underwater for 60 seconds, you will be thrashing around and generally making a great fuss of your predicament; but if I push your head underwater for 10 minutes, you will stop complaining about things.

In any case, the freeze sprays, although they are very cold, they only cool locally, so they can paralyse the nerve endings, but wont actually cause frostbite.
